This commit adds support for Kotlin Coroutines suspending functions to
Spring MVC, by converting those to a Mono that can then be handled by
the asynchronous request processing feature.
It also optimizes Coroutines detection with the introduction of an
optimized KotlinDetector.isSuspendingFunction() method that does not
require kotlin-reflect.
Closes gh-23611
Prior to this commit, the resource handler serving static resources for
Spring MVC and Spring WebFlux would always look at the
`Resource#lastModified` information, derive the `"Last-Modified"` HTTP
response header and support HTTP conditional requests with that
information.
In some cases, builds or packaging tools choose to set this last
modification date to a static date in the past. This allows tools to
have reproducible builds or to leverage caching given the static
resources content didn't change.
This can lead to problems where this static date (e.g. "1980-01-01") is
used literally in HTTP responses and will make the HTTP caching
mechanism counter-productive: the content of the resources changed, but
the application insists on saying it didn't change since the 80s...
This commit adds a new configuration option to disable this support -
there is no way to automatically discard those dates: there is no
standard for that and many don't use he "EPOCH 0 date" as it can lead to
compatibility issues with different OSes.
Closes gh-25845
Prior to this commit, error handlers in the WebMvc.fn and WebFlux.fn
router function builders had to be registered in an unintuitive, reverse
order, due to the filter chain composition model used.
This commit reverses the error handler order, so that more specific
error handlers can come before generic ones.
Closes gh-25541
This commit adds two overloaded methods for each HTTP method in the
WebFlux.fn and WebMvc.fn route builders: one method taking just a
handler function, the other a request predicate and handler function.
After this commit, it is no longer required to provide a String path,
which is particularly useful when nesting routes, and the path would be
"".
Closes gh-25752
This commit introduces a new async(Object) method in the WebMvc.fn,
taking a asynchronous response as argument in the form of a
CompletableFuture or Publisher. This allows for asynchronous setting
of headers and status (and not just body, which was already possible).
Closes gh-25828
We don't expect a browser to save error responses to a file but we
extend this protection anyway since "inline" is only a suggestion
that shouldn't have any side effects.
See reactor/reactor-core#2374
All usages of this API are in tests, which are not checking overflow or
concurrent emissions - so a simple replacement with `try***` equivalents
is fine.
This commit deprecates the `AppCacheManifestTransformer` implementations
since the appcache feature is being removed from the browsers.
Closes gh-25733
UrlPathHelper is often created and used without customizations or with
the same customizations. This commit introduces re-usable, instances.
Effectively a backport of commit 23233c.
See gh-25690
This commit makes several changes in both WebMvc.fn as well as
WebFlux.fn.
- ServerRequest now exposes a RequestPath through requestPath(), and
pathContainer() has been deprecated.
- The PathPredicate and PathResourceLookupFunction now respects this
RequestPath's pathInApplication() in their path-related
functionality.
- When nesting, the PathPredicate now appends the matched part of the
path to the current context path, instead of removing the matched
part (which was done previously). This has the same result: the
matched part is gone, but now the full path stays the same.
Closes gh-25270
MVC data class processor constructs target instance even in case of binding failure, as long as the corresponding method parameter is not marked as optional.
Closes gh-24372
Prior to this commit, MockHttpServletResponse's setCharacterEncoding()
method did not update the contentType property, which violates the
Servlet 2.4 Javadoc for getContentType() and setCharacterEncoding().
This commit addresses this issue; however, some existing tests may have
to be updated as a result of this change.
For example, note how some of the tests in this commit have been
refactored to use MediaType##isCompatibleWith() instead of asserting
exact matches for the value returned by MockHttpServletResponse's
getContentType() method.
Closes gh-25536
Remove convenience Map that is to avoid. The only downside is that
getHandlerMethods requires a transformation but that should not be used frequently.

This commit evolves the solution from M1 by parsing and caching patterns with the
target HandlerMapping's PathPatternParser. This makes it unnecessary for callers to
be aware of pattern parsing.
Closes gh-25312
This commit introduces a way to change the PathPatternParser used in
PathPredicates, by way of a ChangePathPatternParserVisitor. This
visitor is used by both WebFluxConfigurationSupport and
WebMvcConfigurationSupport to make sure the configured parser is used.
Closes gh-23236
This commit fixes a recent regression as a result of 5225a57411
with the determination of non-pattern vs pattern URLs. That in turn affects the ability to perform
direct matches by URL path.
There is also a fix in PathPattern to recognize "catch-all" patterns as pattern syntax.
See gh-24945
This commit introduces a spring.xml.ignore system property
which when set to true avoid initializing XML infrastructure.
A typical use case is optimizing GraalVM native image footprint
for applications not using XML. In order to be effective, those
classes should be initialized at build time:
- org.springframework.util.DefaultPropertiesPersister
- org.springframework.core.io.support.PropertiesLoaderUtils
- org.springframework.web.servlet.function.support.RouterFunctionMapping
- org.springframework.web.client.RestTemplate
- org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver
- org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport
- org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter
- org.springframework.http.converter.support.AllEncompassingFormHttpMessageConverter
- org.springframework.http.codec.support.BaseDefaultCodecs
- org.springframework.beans.PropertyEditorRegistrySupport
Closes gh-25151
Prior to this commit some of the default strategies defined
for the DispatcherServlet weren't included in the default
configuration for both Java and XML configuration.
The following default beans have been added to the configuration
with the name as expected by the DispatcherServlet:
- org.springframework.web.servlet.i18n.AcceptHeaderLocaleResolver
- org.springframework.web.servlet.theme.FixedThemeResolver
- org.springframework.web.servlet.support.SessionFlashMapManager
- org.springframework.web.servlet.view.DefaultRequestToViewNameTranslator
Closes gh-25209
With #25209, DispatcherServlet.properties loading and parsing
will be useless for most of use cases, and it requires
configuration on GraalVM native images.
The purpose of this issue to make such loading and parsing lazy,
only invoked in getDefaultStrategies() if needed.
Closes gh-25257
Prior to this commit, calling the `setResponseBodyAdvice` method would
clear all existing `ResponseBodyAdvice` instances present in the list
before adding provided one.
This behavior is inconsistent with the Javadoc and other
implementations.
This brings the method in line with the existing documentation.
See gh-24204
In many places UrlPathHelper is created and used without any
customizations, in some cases repeatedly. This commit adds a
shared read-only UrlPathHelper instance with default settings.

Prior to this commit, the `VersionResourceResolver` implementations
would write a strong ETag HTTP response header with the resolved version
of the resource (the actual value depending on the chosen strategy).
This approach doesn't work well when combined with HTTP compression.
Web servers disable HTTP response copression in the presence of strong
ETags since mutating the response body would break the contract.
This commit changes this semantic and ensures that weak ETags are used
instead.
Closes gh-24898
This commit makes the default ServerRequest implementation use a pre-
parsed path container, instead of parsing the path for each invocation
of pathContainer().
This commit changes the way RouterFunctions registered to the builder
are composed in both WebFlux.fn and WebMvc.fn.
Prior to this commit, all routes added to the build were composed with
`reduce`.
After this commit, all routes are stored in a special router function,
allowing for more efficient execution and smaller stack traces.
Closes gh-24652
Credentials are not enabled by default contrary to the javadocs.
The credentials support must be enabled via #allowCredentials.

This commit adds the checkNotModified method to ServerRequest in both
WebFlux.fn and WebMvc.fn. Unlike other checkNotModified methods found
in the framework, this method does not return a boolean, but rather
a response wrapped in a Mono/Optional. If the resource has
not been changed, the not-modified response can be returned directly;
if the resource has changed, the user can create a corresponding
response using switchIfEmpty/orElse(Get).
Closes gh-24173
These calls were added in error when trying to fix#22797 and #23775.
They are not needed in 304 scenarios. Those have no response content and
are skipped by ShallowETagHeaderFilter based on the status.
This leaves disableContentCaching invoked only in streaming scenarios,
which was the original intent and should be the only reason for that
method.
See gh-24635
The attribute was previously removed only before exception resolution
in the DispatcherServlet in order to allow error rendering to make an
independent choice on content negotation.
However, Boot rendering happens later in an ERROR dispatch which could
also be a nested dispatch on some servers. So the attribute must also
generally be removed prior to mapping.
We also move the methods where this is done to the base
RequestMappingInfoHandlerMapping class which also deals with the
produces condition and where the producible attribute is added in the
first place.
Closes gh-24466
As per the Javadoc of ConcurrentHashMap its computeIfAbsent
implementation is atomic and hence already synchronized internally,
so we can remove the surrounding synchronization block.

This commit deprecates PathExtensionContentNegotiationStrategy and
ServletPathExtensionContentNegotiationStrategy and also updates code
that depends on them internally to remove that dependence.

This commit updates CORS support in order to check Origin header
in CorsUtils#isPreFlightRequest which does not change how Spring
MVC or WebFlux process CORS request but is more correct in term
of behavior since it is a public API potentially used in another
contexts.
It also removes an unnecessary check in
AbstractHandlerMethodMapping#hasCorsConfigurationSource and processes
every preflight request with PreFlightHandler.
Closes gh-24327
When a request is mapped through a producible condition on an
@RequestMapping, then a failure to find a converter/decoder should be
a 500 because the return type + media type pair were declared by the
controller and that should be possible to render.

Spring Framework 5.2 introduced support for caching @ControllerAdvice
beans; however, this caching was also applied incorrectly to
non-singleton beans.
This commit addresses this regression by only caching singleton
@ControllerAdvice beans.
Closes gh-24157
Prior to this commit, methods in a @ControllerAdvice bean were
registered and invoked twice if the advice was a scoped bean (e.g.,
request or session scoped). In other words, both the proxy bean and the
target bean were wrapped in ControllerAdviceBean instances.
This commit fixes this bug by modifying the findAnnotatedBeans() method
in ControllerAdviceBean so that it filters out targets of scoped
proxies.
Closes gh-24017
Spring Framework 5.2 introduced support for implementing the Ordered
interface in a @ControllerAdvice bean. This support requires that
@ControllerAdvice beans be eagerly resolved from the BeanFactory in
order to invoke the getOrder() method defined in the Ordered interface.
Unfortunately doing so resulted in a regression in that an attempt to
eagerly resolve a scoped @ControllerAdvice bean throws a
BeanCreationException due to the lack of an active scope (e.g., request
or session scope).
This commit fixes this regression by avoiding eager resolution of scoped
@ControllerAdvice beans. As a direct consequence, the Ordered interface
is not supported for scoped @ControllerAdvice beans.
Closes gh-23985
Previously, spring-webmvc and spring-webflux both contained tests
that would create gzipped files, write them to the filesystem
alongside the project's compiled test classes, and configure them to
be deleted on JVM exit. The output location placed the files on the
classpath, polluting it for every subsequent test that used the same
ClassLoader. The test-sources plugin combined with Gradle's use of
worker JVMs, broadens the scope of this pollution to other, downstream
projects in the same build. For example, the tests for
spring-websocket will have a different classpath depending on whether
or not the tests for spring-webmvc have already been run on the same
worker as part of the current build.
This commit updates the spring-webmvc and spring-webflux modules to
introduce a new JUnit Jupiter extension, GzipSupport. This extension
allows gzipped files to be created via an injectable GzippedFiles
class and automatically deletes each created file in an after-each
callback. This ensures that a gzipped file only exists on the
classpath for the duration of the test that needs it, avoiding the
pollution of the classpath of any subsequent tests.
